"everything but Chrome" is incorrect. From article:
"Internet Explorer, Safari and Firefox. The one major Web browser left standing? Google Chrome"
"That said, I should also note that Pwn2Own didn't offer prizes for anyone beating up on other popular Web browsers such as Opera or the Linux operating system."
Additionally:
"None of the hackers targeted Google's Chrome web browser.
However, one should be careful with drawing conclusions about the security of the individual products. Pwn2Own is mainly a hacking extravaganza. Nobody knows who spent how much time on finding security holes and developing the appropriate exploits. Charlie Miller, for instance, told the The H's associates at heise Security that he focused on Safari from the start. He added that it's open to speculation whether it would have taken him the same amount of time to find an exploit in Chrome. In Miller's opinion, Pwn2Own isn't a suitable basis for conclusions about which product is the most secure."
The difference between attacking Safari and Chrome is that once you've found the browser hole, which may well exist in both browsers, you still need to break out of Chrome's sandbox. If one is going to attack a WebKit browser, Safari's definitely the easier choice.
I think that that sentence desperately needed an "on" after the "or".
"Pwn2Own didn't offer prizes for anyone beating up on other popular Web browsers such as Opera or [for beating up on] the Linux operating system" is how I parse it.
"Internet Explorer, Safari and Firefox. The one major Web browser left standing? Google Chrome"
"That said, I should also note that Pwn2Own didn't offer prizes for anyone beating up on other popular Web browsers such as Opera or the Linux operating system."
